This implies Π N and Π D each projects out n-dimensions out of 2n-dimensionaldouble space. The double D-brane is an n-dimensional object in the 2n-dimensional doubledspace. The conventional sense of a Dp-brane is in fact the p-dimensionalintersection of the double D-brane with the physical T n ⊂ T 2n . “T-dualizing a Dp-brane” is to change the orientation of the double D-brane inthe double space by O(n,n) rotation.Here comes your footerPage 20
Conditions for the projectors Projector condition: Null conditions: b.c should be compatible with the self-duality constraint Can also impose the orthogonality conditioni.e. the Neumann direction can be completely specified by N-b.c.Here comes your footerPage 21
